I am trying to print in page mode on the Epson TM-U295 slip printer:
ESC "#" ; Initialize
ESC "q" ; Release
ESC "K" 31 ; Reverse feed 0.82in
ESC "L" ; Select page mode
ESC "T" 3 ; Select top-to-bottom direction
"7/26/2019"
FF ; Print and return to standard mode
ESC "F" 1 ; Set reverse eject
FF ; Eject slip
ESC "q" ; Release
The problem is that after printing the date, the printer just keeps feeding the paper. I have to turn it off to make it stop.
Is there a mistake in my command stream?
You just set the page mode and the print direction, and have not set the page mode print area.
In that case, the default for the area of the TM-U295 printer is the maximum value from 0x0 to 210x480.
Even if only one line of date is written, if printing is started, paper feeding is performed to print all 480 vertical areas.
If you want to feed by the number of lines to print, after setting the page mode, you need to set the page mode print area of only the necessary minimum size before sending the print string.
The corresponding page is in Japanese.

I have a thermal printer "MPT-II" from an unknown Chinese brand, that has both USB and Bluetooth. I can successfully print text using:
Loyverse app on Android
JavaScript
Raw HEX or decimal
However, only using the Loyverse app am I able to input special characters, and by special characters I mean the Danish characters æøå/ÆØÅ.
If I open up any BLE tool on Windows (Bluetooth LE Lab for example), I can select the correct characteristic and send something like 104 101 108 108 111 13 10 which would print "hello" on the printer. I've read a bit about the ESC R and ESC t commands, but how exactly do I set those modes? I've tried prepending it to each command, such as 27 82 1 104 101 108 108 111 13 10 where the 27 82 1 corresponds to ESC R 4 and the 4 corresponds to Denmark I.
According to the printer's manual, it states the following:
GB18030 character set, ASCII characters, user defined characters, bar codes CODE39, EAN13, EAN8, CODABAR, CODE93, ITF, bitmaps.
According to that list, the Danish character set is not supported. I'm not sure how the Loyverse app is doing it correctly, but the text is the same using raw commands and Loyverse, so I don't think Loyverse is converting to a bitmap and sending that data.
So my real question is: How do I send the correct character set for my printer? Maybe the character set is already correct, but the ASCII character for æøå/ÆØÅ are wrong?
EDIT: I have confirmed that something works with the ESC XXXX commands. If I do 27 97 2 followed by my "hello" sequence, the text is printed to the right (right aligned). So that definitely works.. I have tried probably all character sets thus far using ESC R and ESC t but none of them work :(
EDIT 2: I have now tested every single combination of ESC R and ESC t. I went through the entire list printing some Chinese characters, and every single line of 150+ I tried all returned the same Chinese character. So ESC R or ESC t is definitely not the command I should be using to change the charset.
I'm trying to define custom characters on thermal printer NCR 7199.
I used ESC/POS command
ESC & y c1 c2 x d1...dn
and it works fine. But this command can change only characters in range 32-126, and those characters are latin letters and common symbols.
I'd prefer to replace characters with codes 8E-8F, for example, but cannot do it using this command.
Is it possible? Or is there any other ESC/POS command for user-defined characters?
UPD.
It seems like a firmware update can fix this problem. Firmware version on our printer is v99.21, and I saw this in release notes:
v99.25 "based on v99.24"
1. Allowed User-defined characters defined range from 20H to FFH in 7199 Emulation mode
Another user-defined character setting command for Kanji is for printers that support the MBCS character set, which is not what you want.
FS 2
Define user-defined Kanji characters
However, although it is unclear whether NCR 7199 supports it, ESC/POS has the ability to customize the font of the user-defined code page rather than the individual characters.
Please refer to the contents of the following pages.
GS ( E <Function 7>
Copy the user-defined page
GS ( E <Function 8>
Define the data (column format) for the character code page
GS ( E <Function 9>
Define the data (raster format) for the character code page
GS ( E <Function 10>
Delete the data for the character code page
Problem solved by updating firmware.
After updating "Main Firmware" to v99.27 (it seems that version must be greater or equal v99.25) and changing Emulation mode to "NCR 7199" I was finally able to define characters in all range 20-FF.
I am trying to print to a GT800 Zebra printer thru serial port.
I am using ZPL. I want to control the width which is fine in auto mode. To address that in the >^BC> command I am using Auto mode as no other size setting under ^BY works
Following is the code
^XA
^MMT
^PW831
^LL400
^LS0
^BY2,,76^FT225,141^BCN,76,Y,Y,N,A
^FD:RNIP29200082034^FS
^FO225,157^A#N,18,10,E:CAL002.FNT^FD26030-0892R^FS
^FO383,157^A#N,18,10,E:CAL002.FNT^FD08.01.20 12:00PM^FS
^FO225,187^A#N,18,10,E:CAL002.FNT^FDLAMP-DR RH^FS
^FO453,187^A#N,18,10,E:CAL002.FNT^FDXBA3^FS
^PQ1,0,0,Y
^XZ
There is a funny problem. If the ^BC mode = A then if three zeros come together gives issues for eg ABCD29200082034 it prints ABCD29200 and does not complete the barcode. But the other lines are getting printed. But if the data is ABCD29200182034 , there are no issues.
If BC mode = U then even if the code is ABCD29200182034 it prints 292001820347. Note 7 is added in the end.
I am clueless as to what is this issue. I remember facing this same issue in Honeywell printer too once.
Thanks
NOTE : I replaced the 000 with 111 and the problem persists.
ZPL Manual says the following
A= Automatic Mode :This analyzes the data sent and automatically determines the best packing method. The full ASCII character set can be used in the ^FD
statement — the printer determines when to shift subsets. A string of
four or more numeric digits causes an automatic shift to Subset C.
Note , it says a string of four or more numeric digits causes an automatic shift to subset C, but when the same string is 290010 it has no issues. I am really lost
I need to be able to print Hebrew characters on my Epson TM-T20ii. I am trying to get my printer to switch to character code page 36(PC862) using
ESC t36
for some reason the printer is switching to code page 3 and then printing the number 6.
Is there a way to let the printer know that the 6 is part of my command?
If you know of a different workaround please comment below.
Thanks
You are making a mistake, you aren't meant to replace n with an actual number.
The proper syntax in your case would be ←t$
Explanation: the manual says "ESC t n", n referring to the page sheet, however you don't replace n with a number rather with the ASCII character n, so in your example 36 = $ because $ is the 36th character on the ASCII table.
i searched google but can't seem to find a working solution.
the situation is unique. i need to "add" lines with a comment at various times. whenever i press the F9 key, a line number will dispaly followed by a colon ":" char and then i enter some comments at the line number and cursor position.
the running output should look like this:
001: startup time
002: watched tv
003: |
where "|" is the last cursor position at runtime, waiting for me to enter some text.
but instead, when i run the program and press the F9 key, i get this:
001:
002:
003:
|
where "|" is the last cursor position at runtime, waiting for me to enter some text.
how can remove that (last) blank line in a memo?
Add() inserts a line break after the inserted text. If you do not want the line break, then use the SelText property instead, eg;
Memo1.SelStart := Memo1.GetTextLen;
Memo1.SelLength := 0;
Memo1.SelText := '003: ';
